Controlling a 3d model

[A Former User]

@hareeshqt said:

can we visualize the application for the controls and the 3D model in the same window?

You mean like this: kinematics demo?

[hareeshqt]

@Wieland Yes exactly...!!!!

[A Former User]

@hareeshqt Great. So, yes it's possible, just what I did in the demo :-) Easiest way is to have a Qt3D scene in QML and use QtQuick controls as overlay, like:

main.qml

import QtQuick 2.5
import Qt3D.Core 2.0
import Qt3D.Render 2.0
import QtQuick.Scene3D 2.0
import QtQuick.Window 2.2
import QtQuick.Controls 1.4

Window {
    id: mainWindow
    visible: true
    width: 800
    height: 600
    // ...

    // Qt3D scene
    Scene3D {
       // ...
    }

    // Overlay...
    Button {
       // ...
    }
}

@Wieland Thank you..'ll try and let you know

[hareeshqt]

@hareeshqt should we have Qt3D module and opengl for doing this...?

[A Former User]

@hareeshqt In the .pro file you need QT += qml quick 3dcore 3drender.

[hareeshqt]

@Wieland and which application would be better widget or consol or....?

[A Former User]

@hareeshqt "Qt Quick Controls Application"

[hareeshqt]

@Wieland but if we use the Qt Quick Controls Application, we are not getting the .pro file is there any method.....?

[A Former User]

@hareeshqt In Qt Creator, click "New project", select "Qt Quick Controls Application", click "Choose", enter a project name, click "Next", click "Next", click "Next", click "Finish". Your project folder now contains some files, include a .pro file.

[hareeshqt]

@Wieland by doing that I got .qmlproject file. Is it the same?

[A Former User]

I'm pretty sure you didn't select "Qt Quick Controls Application" but "Qt Quick Controls UI".

[hareeshqt]

@Wieland Ya OK got it...thank you

[hareeshqt]

@hareeshqt Ok so how can I import my 3d model from blender to Qt ?

[A Former User]

@hareeshqt Take a look at the examples. Maybe start with this one.

[hareeshqt]

@Wieland Ok many thanks....

[hareeshqt]

@Wieland Hi, I'm trying the example suggested by you and got all the required files but how can we get the (.geom) file?

[A Former User]

@hareeshqt Oh, yes, that's a bug in example shipped together with the latest Qt installers. You can get all files from here: http://code.qt.io/cgit/qt/qt3d.git/tree/examples/qt3d/wireframe

(You don't need to file a bug report for this, I already did this some time before, see QTBUG-50859)

[hareeshqt]

@Wieland Hi, everything is ok now but after building, in the main.cpp file for #include<window.h> it's saying no such file or directory exists. Help me please.....

[A Former User]

@hareeshqt You can find window.h and window.cpp in http://code.qt.io/cgit/qt/qt3d.git/tree/examples/qt3d/common.
